DS1302 RTC module running too fast

I am using a DS1302 RTC module with an Arduino Mega 2560 Rev 3. I follow steps on this website since I have no experience with RTC module before. Here are the outputs I am getting.

17:15:21.835 -> Current Date / Time: 26/2/2023 17:15:44 17:15:26.830 -> Current Date / Time: 26/2/2023 17:16:13 17:15:31.856 -> Current Date / Time: 26/2/2023 17:16:42 17:15:36.853 -> Current Date / Time: 26/2/2023 17:17:11 

As you can see from the above output, the DS1302 is running five times faster than the real time (output past 30 seconds as real word past 5 seconds). Same thing happened if use different codes with different libraries.

Does this mean the RTC module itself is broken, or I can modify RTC module's speed with code?

//This code is to use with DS1302 RTC module, it permits you to setup the actual time and date //And you can visualize them on the serial monitor //This code is a modified version of the code provided in virtuabotixRTC library //Refer to https://Surtrtech.com for more information #include <virtuabotixRTC.h> //Library used //Wiring SCLK -> 6, I/O -> 7, CE -> 8 //Or CLK -> 6 , DAT -> 7, Reset -> 8 virtuabotixRTC myRTC(6, 7, 8); //If you change the wiring change the pins here also void setup() { Serial.begin(9600); // Set the current date, and time in the following format: // seconds, minutes, hours, day of the week, day of the month, month, year myRTC.setDS1302Time(15, 15, 17, 7, 26, 2, 2023); //Here you write your actual time/date as shown above //but remember to "comment/remove" this function once you're done //The setup is done only one time and the module will continue counting it automatically } void loop() { // This allows for the update of variables for time or accessing the individual elements. myRTC.updateTime(); // Start printing elements as individuals Serial.print("Current Date / Time: "); Serial.print(myRTC.dayofmonth); //You can switch between day and month if you're using American system Serial.print("/"); Serial.print(myRTC.month); Serial.print("/"); Serial.print(myRTC.year); Serial.print(" "); Serial.print(myRTC.hours); Serial.print(":"); Serial.print(myRTC.minutes); Serial.print(":"); Serial.println(myRTC.seconds); // Delay so the program doesn't print non-stop delay(5000); }
